Functions

func CleanCgoStruct

func CleanCgoStruct(input any) any

CleanCgoStruct cleans roundtripped object from a cgo-generated structure. It deletes padding and reserved fields, then converts object keys to lowerCamalCase.

func Roundtrip

func Roundtrip(input, ptr any, options ...Option) error

Roundtrip marshals the input to JSON then unmarshals it into ptr. This is useful for converting between structures.

Types

type Option

type Option func(*json.Decoder)

Option sets an option on json.Decoder.

var DisallowUnknownFields Option = func(d *json.Decoder) { d.DisallowUnknownFields() }

DisallowUnknownFields causes json.Decoder to reject unknown struct fields.
